Eye disorders: Glaucoma
Definition
It is a common eye condition where the optic nerve, which connects the eye to the brain, becomes damaged.
-
-
Diagnostic tests
-
optic nerve and/or retinal nerve fiber layer imaging (using optical coherence tomography),
-
-
-
-
Pathophysiology
It is caused by an increase in intraocular pressure. Axons of retinal ganglion cells travel through the optic nerve carrying visual information from the eye to the brain. Damage to these axons causes ganglion cell death with resultant optic nerve atrophy and patchy vision loss. Elevated IOP (in unaffected eyes, the average range is 11 to 21 mm Hg) plays a role in axonal damage, either by direct nerve compression or diminution of blood flow.

Nursing intervention
Assessment
Subjective data
-
Family history of diabetes, ophthalmic conditions
Objective data
Assess for signs of infection, discharge, foreign objects and scaring
-
Nursing diagnosis
Disturbed sensory perception may be related to altered status of organ evidence by progressive loss of visual field
